Deuteronomy 28:9-14

9The LORD will establish you as a people holy to himself, as he has sworn to you, if you keep the commandments of the LORD your God and walk in his ways. 10And all the peoples of the earth shall see that you are called by the name of the LORD, and they shall be afraid of you. 11And the LORD will make you abound in prosperity, in the fruit of your womb and in the fruit of your livestock and in the fruit of your ground, within the land that the LORD swore to your fathers to give you. 12The LORD will open to you his good treasury, the heavens, to give the rain to your land in its season and to bless all the work of your hands. And you shall lend to many nations, but you shall not borrow. 13And the LORD will make you the head and not the tail, and you shall only go up and not down, if you obey the commandments of the LORD your God, which I command you today, being careful to do them, 14and if you do not turn aside from any of the words that I command you today, to the right hand or to the left, to go after other gods to serve them.
